SPECIFILCATION forming part of Letters Patent No. 260,504, dated July 4, 1882.

i Application filed Maron 11, 1882. (No model.)

`To all lwhom 'it may concern Be it known that we, GEORGE C. STEVENS and CALVIN D. READ, of Ayer, in the county purposes, the object being to provide a spindle with a tapering bearing to admit ot' compensation for wear, and to combine with the spindle lubricating devices so constructedand arranged as to insure a regular and uniform oiling ofthe parts and a consequent free revolution of the spindle.

The invention consists in the improved con-y struction and combinations ot' devices hereinafter fully described, and pointed out' in the claims.

In the draWings,Figure1 is a side elevation of a spindle and its attachments constructed in accordance with our invention. Fig. 2 is a 4central longitudinal section of the same, and Fig. 3 is a modication, shown partly in section.

A represents the holder for the bolster and step or" the spindle', provided with a lower loop or bearing, B, adapted to lreceive a lower oilreceptacle, O,whichis removably secured in the bearing by a set-screw, G. The oil-receptacle C is provided With a central boss or hub, D, having a vertical perforation, d, to receive the step E of the spindle, and ahorizontal perforation, @,uear the bottom of the hub,which communicates with the perforation d to feed oil to the latter to lubricate the stepEof the spindle.

F represents the upper cylindrical chamber of the holder, provided with inner shoulders, f and f', and a depending tube or shell, Gr, the latter having a fixed collar, H.

The spindle I passes through the chamber F and its shell Gr, and is provided with a taperin g bearing, t', which bears :in a corresponding bolster loosely mounted on-said bearingt of the spindle, and may be removed after removing the cover of the receptacle F.

The bolster J is arranged within the chamber F.. This bolster is provided with a horizontal perforation, j, and a vertical perforation, j', for a purpose hereinafter explained.

An `oil-receptacle, L, is rigidly mounted on the spindle below the chamber F, andis adapted to revolve with the spindle. It is provided in'teriorly at its lower edge with an annular groove, Z, to receive the end ot' a spirally-bent tube, M, which latter passes through a perforation, h, of the collar H, and into thechamber F through a perforation, h, of the latter.

Any suitable whirl, N, is mounted on the spindle to revolve the latter by means of a driving-belt. v The oil-receptacles C and L. and the chamber F are provided with suitable caps or covers, a', x', and x2. l l

The step E of the spindle receives its oil through the horizontal perforation e, formed inthe hub D, from the oil-receptacle', which will supply oil to the step as long as there is any oil in the receptacle C.

Thetapering bearingz' of the spindle islubricated by means of the tube M, which, as above described, has its lower end bent spirally and arranged within the revolving oil-receptacle of the spindle.

The revolution of the oil-receptacle causes v the oil to low up through said tube into the chamber F,between the latter and the bolster J, and through the perforation j of the latter to the tapering bcaringz' of the'spindle.

The lower end of the tube enters the annular groove l of the revolving oil-receptacle, so that oil will be fed to the spindle as long as there is any in the reservoir.

1f at any time the oil should rise above the bolster J, between the collar of the latter and the chamber F, it will flow into the vertical perforation j of the bolster and pass back through the shell Gr to the oil-receptacle.

The tapering bearing i of the spindle admits of the vertical adjustment ot' the spindle to compensate for wear.

The upper end of the holder is provided with a horizontal tlan ge, a, adapted to receive a bolt, A,Which pivotally secures the said holder to theV rail A2 of the spinning-frame. Said ange is also perforated to receive screws a', adapted to have their upper ends bear against the rail A2 of the frame. The spindle may be adjusted Slightly to make it plumb by means of the screws a. in the holder. The'spindle ICO thus described will be uniformily lubricated, and will revolve easily and regularly.

It will be apparent that many slight changes in the form and construction of our improvement may be resorted to without departing from our invention. For instance, as illustrated in Fig. 3, instead of extending the tube M up into the chamber' F, a rib or enlargement, z, may be formed on one side ofthe shell G, and perforated vertically to communicate with the chamber F and horizontally to receive the upper end of the tube M.

We do not limit ourselves to the precise construction shown and described, but reserve to ourselves the right to make such alterations in form and construction as may properly fall within the scope ot' our invention.

Having fully described our invention, what we claim as new, and desire to secure by Let-v ters Patent, is-

1. The combination, with a spindle and a bolster for supporting its upper portion, of an oil-receptaele located below the bearing and attached to the spindle, and an oil-conduit extending from said bearing downwardly and into the oil reservoir or receptacle, substantially as set forth.

2. The combination, with the upper chaluber of the holder, of a spindle passing th rough said chamber, and provided below the latter with a revolving oil-receptacle, a bolster snrrounding the spindle within said chamber, perforated both vertically and horizontally, and an oil-tube whose upper end extends within said chamber, while its lower end is spirally bent within the revolving oil-receptacle, whereby oil is fed upwardly by the revolution of the oil-receptacle, substantially as set forth.

3. The combination, with the upper chamber of the holder and its perforated bolster, of a spindle having a tapering bearing revolving in said bolster, and a revolving oil-receptacle provided atthe lower edge of its interior with an annular groove, and an oil-tube whose upper end extends within said chamber to lubricate the tapering bearing of the spindle,while its lower end is arranged within the revolving oil-receptacle and spirally bent to extend into the annular groove of the latter, substantially as set forth.

4. rlhe combination, with the spindle, bolster, and the upper chamber of the holder, provided with a downwardly-projecting tube or shell, and the revolving oil-receptacle of the spindle, of an oil tube or passage whose lower end is spirally bent and arranged within said revolving oil-receptacle, while its upper end communicates with said upper chamber to lubricate the tapering bearing of the spindle, substantially as described.
